Quite frankly, the unconstitutional silencing of certain point of views (e.g., anti-vax) actually hurt the sane arguments on the other side.
Let me explain:
First of all, it is unconstitutional. I know, I know. Twitter, Facebook are private. But when private companies have swallowed up 75%+ of the public discourse arena then constitutional protections must extend to them, as well. Its plain logic.
More importantly, as a free society we encourage public discourse – partly because of its evolutionary ability to sift out the garbage. It does not happen right away but eventually, nonsensical arguments like those espoused by the anti-vaxxers are exposed for the utter garbage that they are. Without the dialogue, this will never happen and the garbage arguments will forever remain hidden beneath the surface waiting to trap its next victim.
